lSpecification of Letters Patent.

To all 'whom it may concern: Y

Be it known that I, JUDsoN BUCHANAN, a citizen kof the United States,residing at Chattanooga, in the county of Hamilton and StateofTennessee, have invented a new andl useful Improvement in Ilows, ofwhich the following is a specification, reference being had to theaccompanying drawing.

My improvement relatesv to plows having said .disks and is amodification of the mech-r anism made the subject-matter of my Pat- -entNo. 910,496, dated January 26,1909.

In the accompanying drawings, Figure 1 -is a plan of a plow embodying myimprovement; Fig. 2 is a side elevation of a portion of the same plow;Fig. 3 is a sectional elevation of the mold-board or disk-liftingmechanism; Fig. 4 is a sectional ldetail view on the line 4-4 of Fig. 1,showing one of the disks and a portion of the disk post to which saiddisk is attached; Fig. 5 is a horizontal transverse section of one ofthe disk mately on the line 6-6 of Fig. @looking toward the left; Fig. 7is an upright detail section along the axis of the oscillating gear.

Referring to said drawings, 1 is the land wheel and 2, 2 are therfurrowwheels ordinarily used in such plows.V Said wheels constitute thecarrying wheels for the plow. The frame, in the form shown, comprises abeam, 3, having its ends, 4, turned laterally, and the furrow wheels, 2,are secured to said ends by means of crank-form axles, 5, resting inupright bearings, 6. 'Ihese wheels and the manner of their attachmentmaybe of any well known form. The middle of the beam, 3, is shown bent`laterally Vtoward the same side as are the ends, 4, to form a laterallyextended orl oset approximately straight portion, 9. The frame furthercomprises a horizontal semi-circular section, 7, secured to the rearside of the beam ,'(the `side toward` the land wheel, 1), and the land.wheel is secured to said semi-circular piece. From said portion, 9,'ofthe beam rises an upright housing, 10, in which the disk posts areconfined and have their up and vdown movement, said housing forming waysfor said posts. Said housing is rectangular and oblong inhorizontalcross section and open above and below and hasl at its lowerend an extension, 10a, which is a continuation of the rear'side wall(the wall toward the land wheel, l), and said extension is'appliedflatwise against the front side of the beam, and bolts, 11, extendthrough said extension and said beam and rigidly secure said housingtothe beam. Within said housing is located anoscillatory gear, 12,loosely surrounding a bolt, 13, having' a neck, 13a, extending throughthe rear `wall of said housing and bearing a nut, 13b.'

On the front end of its hub, 12a, the gear,

12, has an upright channeled head, 12b, in whichlies the lower 'end of arack, lever, v14, thebolt,13, having-a neck, 13, extending through saidlever and bearing anut, 13, binding said lever to said head. And on theouter face of the adj aoentwall of said housing is a toothed rack, 8,adapted for engagement by said lever. At 'each side of said gear, 12, isan upright disk post, 15, of reotangular cross section'and of properdimensionsto fit slidably insaid housing, and being channeled at theside of said gear to receive the latter and having teeth, 15a, in saidchannel meshing with the teeth at that side of said gear. Thus said'twoVdisk posts are supported by said gear and adapted to move simultaneouslywith saidf gear, the movement of said gear being oscillatory while themovement 'of said 4posts is in upright lines. The lower end of each diskpost is turned horizontally forward (as may be see-nin Figs. 1 and 6),and each such end supports a bearing, 16, which receives a journal, 17,on a disk, 18, said journals being, respectively, so directed as toplace the centers of the disks in a plane parallel to the draft line andthe disks are directed oppo- -sitely and away from each other, atproperangles, conformably to the opposite drafts.

As shown, the disk posts` are arranged in a plane parallelV to the draftline and the disks are at one side of the posts and so arranged thattheir` centers lie in a verticalplane'parallel to the draft line. kBymovingV the track lever in either direction, .one of the disk i Patentedsept. '7, 1909."

posts and the disks supported thereby will rise while the other diskpost and disk supported thereby will descend; and by engaging said racklever in the rack, 8, at any ,desired point on the latter, the positionsof said disks may be fixed. As will be readily understood from aninspection of the drawings,

either disk may be forced to its lower limit (the other at the same timegoing to-its upper limit), or the vtwo idisks may beset horizontallyopposite each other in position for moving the yplow without working.

To the rear face of the laterally-extended portion, 9, of the beam, 3,is applied a horizontal bracket, 19, and at the center of saidsemi-circular frame section, 7, a tongue, 20,; is hingedto. said bracketpiece by means of .an upright journal, 2l, vwhereby said tongue -isfreeto swing thro-ugh half a circle across Saidsemi-circul'ar piece, 7.

Vsubstantially as'dehsciti'bed.

said semi-.circular piece, 7, for the purpose of reversing the draft.vyIn Fig. .1 said tongue vis set for draft toward theleft. Said tonguemay be secured in its two positions by any `suitable means, as, foreXaniple,.a latch mechanism ('notshown) engagin a notch, Y22,;in

aid latch mechanism does iiot'consti-tute a portion of the presentinvention, Vand hence I deem it unnecessary to illustrateand-describe.thesame .tion of the frame laterally, and still furtherextendingthe frame Vlaterally by means of .theliousing 10, roomA isafforded for mounting the disks in such manner as to clear the frame. gf
